PTFE Capillary Tubing
Our tubing is available in AWG sizes from 0 to 30, with inner diameters (ID) ranging from 0.3mm to 8.38mm, and outer diameters (OD) from 0.6mm to 9.38mm. With wall thicknesses between 0.15mm and 0.50mm, our tubing provides excellent durability and performance across various applications.
PTFE Capillary Tubing Manufacturing
The extrusion manufacturing method is commonly used to produce PTFE capillary tubing.
The manufacturing process include the following steps:
- Raw Material Selection - High-quality virgin PTFE resin and pigments (for colored tubing) are sourced.
- Preforming - The PTFE resin is compressed into a cylindrical billet under controlled pressure.
- Extrusion - The preformed billet is extruded through a specialized die to achieve the desired capillary tubing diameter and wall thickness.
- Sintering - The extruded tubing undergoes a high-temperature sintering process to fuse the PTFE particles.
- Cooling & Calibration - The tubing is gradually cooled and precisely calibrated to maintain tight tolerances.
- Cutting - Tubing is cut to specific lengths.
- Quality Inspection - Dimensional accuracy, surface finish, wall uniformity, and color consistency (for colored tubing) are rigorously tested to meet industry standards.
